what color vest tux matches brown bms dresses?

we had brown bm dresses.

the dresses had a champagne (euro taupe) sash, so the vests & ties matched that color.

the dads wore a black vest & a tie that had black & brown stripes to match our moms who also wore brown.

there are a lot more pics in my review, but this gives you a basic idea:

My friend had brown bridesmaids dresses and the guys wore black tuxes with ivory vests and ties. It looked very nice! I don't like the idea of brown tuxes...makes me think of napoleon dynamite
